| Abstract |
|
The interstitial lung diseases(ILD) comprises a large, heterogeneous group of disorders characterized
by derangement of alveolar walls and alveolar capillary unit causing restrictive pulmonary
dysfunction and disordered gas exchange. It is rare, especially in children, and the opinions on
investigation and treatments are controversial. The classification of adult ILD is applied to that of
children. But considering occurrence during the developing state of lung and immune systems, we
should be more cautious because the clinical manifestations and prognosis will be different from
those of adults. In 1995, Katzenstein named a unique type of ILD, chronic pneumonitis of infancy
(CPI) for the first time. CPI is characterized by marked alveolar septal thickening, striking type II
pneumocyte hyperplasia, and eosinophilic alveolar exudate containing numerous macrophages. We
report a 14 month-old girl, who had continuing respiratory difficulty and cyanosis after upper
respiratory infection, could not sustain oxygen saturation and was finally diagnosed as CPI by
histologic examination. |
